For my Automotive carbureted applications, I have this air/fuel monitor from Edelbrock. It uses an oxygen sensor and allows me to tune the carburetor(s) for precise mixture based on the color of the led readout. (Plus it allows me to monitor air/fuel mixture while the vehicle is in operation.) I would like to have this versatility with my jet powered olds marine motor. But can't think of any way that it would work due to the discharge cooling water being introduced thru the transom exhaust system.
Am I stuck using vacuum gauges to set air/fuel ratio on my jetboat, and not being able to constantly monitor a lean/rich carbureted condition?

*edit* would this require a specialty designed exhaust manifold to allow for the oxygen sensor?*
